Electric Heat PTACs vs. Heat Pump Models: Which One Fits Your Space?

🏠 Introduction: One Unit, Two Options

If you’ve ever stayed in a hotel or lived in an apartment with a Packaged Terminal Air Conditioner (PTAC), you know how convenient they are. PTACs combine heating and cooling in one unit, saving space and simplifying comfort. Instead of needing both a furnace and an air conditioner, you get year-round climate control through a single wall-mounted system.

But here’s the big question: should you go with a PTAC that uses electric resistance heat, or a PTAC with a built-in heat pump?

At first glance, they look the same. Both units slide into a wall sleeve, run quietly, and can keep a guest room or apartment comfortable. But when it comes to energy efficiency, climate suitability, and long-term costs, the difference between electric and heat pump models is huge.

In this guide, I’ll break down how each works, which one is better for different spaces, and what to expect in terms of performance and costs. By the end, you’ll know exactly which PTAC is the right fit for your home, rental property, or business.

🔌 How Electric Heat PTACs Work

An electric heat PTAC is the simpler of the two designs. Inside the unit, heating comes from electric resistance coils—basically metal wires that get red-hot when electricity runs through them, just like a toaster. A fan blows air across the coils, and voilà: warm air fills the room.

✅ Advantages of Electric Heat PTACs

• Reliability: Electric heating works no matter the temperature outside. Even if it’s -10°F, those coils will still get hot.

• Simple design: Fewer moving parts mean fewer breakdowns.

• Lower upfront cost: Electric PTACs are usually cheaper than heat pump models.

• Fast heat: Resistance coils heat up instantly, so you get warmth right away.

⚠️ Downsides of Electric Heat PTACs

• Energy hogs: Electric resistance heating is one of the least efficient methods. The U.S. Department of Energy notes that it converts nearly all electricity into heat, but electricity itself is expensive compared to natural gas or heat transfer methods .

• Higher bills in winter: Running a 2.5 kW electric heater all day can send utility costs skyrocketing, especially in regions with long, cold winters.

👉 Think of electric heat PTACs as the reliable workhorse: always ready, simple to maintain, but not the cheapest long-term option.

❄️ How Heat Pump PTACs Work

Now let’s look at heat pump PTACs. Instead of generating heat with coils, these units use the same technology as an air conditioner, but in reverse.

Here’s the short version:

• In summer, the PTAC moves heat out of your room (cooling).

• In winter, it reverses, moving heat into your room from outside air.

This method of heat transfer is far more efficient because you’re not creating heat—you’re just moving it around.

✅ Advantages of Heat Pump PTACs

• Energy efficiency: Heat pumps can deliver up to three times more heat energy than the electricity they consume .

• Lower operating costs: If your winters are mild, you’ll save significantly compared to electric heat.

• Environmentally friendly: Less electricity use = lower carbon footprint.

⚠️ Downsides of Heat Pump PTACs

• Cold-weather limits: Heat pumps struggle in very cold climates (below 30–35°F). At those temps, there isn’t enough heat in the outside air to transfer inside.

• More complex: With extra valves, compressors, and refrigerant lines, there’s a greater chance of repairs.

• Slightly higher upfront cost: You’ll pay a little more upfront for the efficiency benefits.

👉 Think of heat pump PTACs as the energy-smart option: efficient, cost-saving in the right climate, but not always reliable in freezing conditions.

🌎 Climate Considerations: Where Each Model Works Best

The biggest factor in choosing between electric heat and heat pump PTACs is climate.

🔥 Cold Climates (Northeast, Midwest, Mountain States)

• Winters often dip well below freezing.

• Heat pumps become inefficient, running constantly but providing little warmth.

• Electric heat PTACs win here because they’ll always deliver heat, no matter how cold it gets.

🌤️ Mild to Moderate Climates (Southeast, Pacific Northwest, Coastal Areas)

• Winters are short and rarely dip below freezing.

• Heat pumps excel in these regions, offering huge energy savings compared to electric coils.

🌐 Hybrid Approach

Some PTAC units actually include both a heat pump and electric backup heat strips. These “dual-mode” PTACs use the heat pump in mild weather and automatically switch to electric heat when it gets too cold. This offers the best of both worlds.

💵 Energy Efficiency & Cost Breakdown

This is where the decision often becomes clear.

Example: 12,000 BTU PTAC with 2.5 kW Electric Heat

• Running 2.5 kW of heat for 8 hours/day uses 20 kWh daily.

• At an average electricity cost of $0.15/kWh, that’s $3.00 per day or about $90/month just for heating one room.

Example: 12,000 BTU PTAC with Heat Pump

• The same unit, using a heat pump, may only use 6–8 kWh daily in mild weather.

• That’s $1.20/day or about $36/month—a huge difference over time.

In a hotel with 50 guest rooms, that difference could add up to thousands of dollars per season.

🔧 Installation & Maintenance Differences

Both electric and heat pump PTACs install the same way:

• Slide into a wall sleeve

• Plug into an electrical outlet (usually 208/230V)

• Vent directly outdoors

Electric Heat PTAC Maintenance

• Minimal upkeep: clean the filter, wipe the coils, and check the drain pan.

• Coils are durable and rarely fail.

Heat Pump PTAC Maintenance

• Requires seasonal coil cleaning.

• Refrigerant circuits should be checked periodically.

• More moving parts = higher long-term repair risk.

🏨 Real-World Use Cases

Hotels & Hospitality

Hotels often choose electric heat PTACs for one simple reason: reliability. Guests expect a warm room no matter the weather, and electric resistance always delivers.

Apartments & Condos

Tenants paying their own utility bills often prefer heat pump PTACs for efficiency. Landlords in mild climates may also prefer them to advertise “energy-efficient heating and cooling.”

Vacation Rentals & Airbnb

Owners tend to choose electric heat PTACs to avoid service calls. For short stays, the difference in energy cost is negligible compared to guest comfort and simplicity.

✅ Final Verdict: Which PTAC Should You Choose?

Here’s the bottom line:

• Choose an electric heat PTAC if:

  • You live in a cold climate with freezing winters.

  • You prioritize reliability and simplicity over energy efficiency.

  • You manage hotels or rentals where guest comfort is non-negotiable.

• Choose a heat pump PTAC if:

  • You’re in a mild climate where winters rarely go below 30°F.

  • You want lower monthly utility bills.

  • You’re looking for a greener, more efficient option.

For many property managers, the ideal setup is a hybrid PTAC with both heat pump + electric backup—offering efficiency most of the year and reliable performance in extreme cold.

👉 The Amana Distinctions 12,000 BTU PTAC Unit with 2.5 kW Electric Heat is a great choice for hotels and small apartments in colder regions. But if you’re in a milder climate and want lower bills, Amana’s heat pump PTAC models may save you money long-term.
